Many if not most Christian evangelical denominations insist that they are the only ones who 100% understand the nature of God.  They each believe everyone else is wrong to one degree or another. There sometimes seems to be more arguing with fellow Christians among themselves than there is any sharing of the Word with those outside their current brand of beliefs. In that regard it is nice to see at least one Christian organization that is not out to prove everyone else is wrong. click the following link to see an article by a Quaker author about being peacemakers.  http://www.friendsjournal.org/personal-peacemaking

The above article is from an August 2008 Friends Journal but is timeless in its advice. It covers 21 tips on personal peacemaking but could also be applied at the denominational level. To tweak your curiosity I will include a few of the tips here along with a brief personal perspective on what they might mean in regards to inter-denominational squabbles that occur regularly today.

• Making fun of the person you are in conflict with, or engaging in sarcasm or ridicule, is poison.

Ridicule of our opponents on Christian issues seems to be almost the norm today as it is in our current political environments. Of course when we are ridiculed we immediately know that it is a poison to any rational debate. Even various theologians seem to use this vehicle against those who disagree with them.

• Judging a person or deciding “who is wrong and who is right” is just another form of blaming.

Jesus had a lot to say about judgment and this is just another way to say what he said.

• We are responsible at all times for choosing behavior that meets our highest moral/ethical standards

The Golden Rule should be how we treat everyone; even those who we disagree with.

• Blame is not a helpful concept.

We should quit trying to prove everyone else is wrong and just go about our lives as Jesus taught us by treating each of our brothers, both Christian and non-Christian with respect.  Creating over 35,000 different versions of Christ is harmful to each of us and to the Body of Christ in general. These conflicts are definitely not in the instructions Jesus gave us.
